SPRING.

SPECIFICATION forming part of Letters Patent No. 710,502, dated October 7, 1902. Application filed February 27, 1902. Serial No. 95.885. (N0 model.)

To (LU whom may concern:

lie it known that I, MOSES II. NABER, acitizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Springs, of which the following is a specification.

The object of my invention is to provide an improved spring adapted for use in all structures which contemplate the employment of springs where it is desired to provide a yielding or rocking connection between a lower base and an upper body of any character whatever; and my invention consists in an improved form of spring adapted to be employed in such relation and location.

'While it maybe apparent from the accompanying disclosure of my invention that its range of use is not limited to any special class of structure, such as chairs or seats, I have illustrated its application and use in connection with chairs as a convenient type of device to which it is well adapted.

In the accompanying drawings, which illustrate exemplifications of my invention, Figure 1 is a bottom plan view of a form of spring embodying my invention. Fig. 2 is a side view of the same shown as applied to any suitable structure having a lower base and a frame, and Fig. 3 is a bottom plan view of a similar form of spring having the coils extended in opposite directions.

In the drawings, A designates a framesuch, for example, as a chair-body or seatframeand B a base, which may be of any desired construction and exemplify the upper and lower portions of a structure between which a yielding or rocking connection is provided by the springs of my invention.

In Figs. 1 and 3 the springs are shown in their inverted position in order to more clearly illustrate the construction of the base portion, and at the left of Fig. l the wing is broken away to better show the mode of attaching the top sections.

The springs are made of steel wire and are arranged and disposed between the base and the body in any manner suitable to the use for which the structure isintended. For example, in the application of the springs to chairs, as shown in the drawings, the springs are placed oppositely at the front and rear, it being understood that two springs are associated together and are oppositely disposed.

The springs are sectional in construction, and the section s of each spring is formed from a suitable length of wire consisting of a horizontal cross-piece 1 of a length suitable to the size of the structure with which the springs are to be associated. At the opposite ends of the cross-piece the wire is slightly bent in an angular direction, as at 2, and is then extended laterally to form the legs 3, which are substantially in a plane parallel to the plane of the cross-piece I. At the ends of the legs the wire is bent downwardly to form wings bearing upon the structure and to furnish means for attaching the springs thereto. In the preferred form of this exemplification the end of each leg 3 is developed into one or more vertical coils 4, which preferably are angular to the legs and extend in the same general direction as do the angular portions 2, as shown in Fig. 3. The wires in extension of the coils are directed inwardly toward each other to form the arms 5 and terminate in the wings 6, which bear upon the frame of the structure. The wings are formed by curving the wire into suitable shape to provide an extended bearingsurface, and the inner ends of the wire are bent at 7 around the arms 5 and extended to the center of the wings, where they terminate in eyes 8 to receive attaching-bolts, to which the nuts 9' are secured.

Each of the portions 3 ofeach spring is formed with a wing 9, similar in all respects to the wings 6 of the portion 8, and the wire extends laterally to form outwardly-directed arms 10, which preferably are developed into one or more vertical coils 11. The wire extends inwardly from the coils to form the leg 12 and is then coiled one or more times about the cross-piece 1, as at 13. The coils 11 of the portions 5' may extend in substantially the same direction as the coils at of the portions .9, as shown in Fig. 1, and all may be either angular to the cross-piece, as at the left of this figure, or may be substantially in extension thereof, as at the right thereof, or they may be angular in opposite directions, as shown in Fig. 3, to form divergent coils.

In assembling the springs upon the body and base of the associated structure the section 5 preferably becomes the lower member,

and the wings thereof may be intermediate or outside the cross-piece, according to the purposes desired. For example, the section 8 is attached to the base B so that the wings of the opposing sections 8 are placed relatively near together and the wings of the sections 3 are held Widely separated, or the section 8 is attached to the base with the wings extending beyond or outside the cross-piece, thereby reversing the relative separation of the wings. The wings form extended bearingsurfaces and are clamped tightly against the associated parts of the base or frame of the passage of the wire around the arms 5 and 10, whereby the strain is distributed around the periphery of the wing.

The springs may be set near together or far apart to provide for use in structures of various sizes and to provide difierent spring effects, as the disclosure herein is employed merely to demonstrate the general purpose of the use of the invention, which may be employed between any suitable base and sution having a cross-piece, wings at the ends I of and lateral to the cross-piece, and sections on opposite ends of the cross-piece, each section having a wing lateral to the cross-piece and on the opposite side thereof to the wings of the continuous section.

2. A spring consisting of a section having a cross-piece, lateral wings at the ends thereof, and a section on each end of the crosspiece and having a wing, the wings extending inwardly and the wings of the first section being on the opposite side of the cross-piece with relation to the wings of the other sections.

In testimony whereof I affix my signature in presence of two witnesses.
